PORATION OF CALIFORNIA ELECTRODE SUPPORTING Application filed May 7, 1930, Serial No.

This invention relates to a. means for hangmg or supporting electrodes in electrical pre cipitators by providing, in addition to the main hanging means normally supporting the electrode on a suitable support in such manner that the electrode hangs in vertical position, auxiliary hanging means connected to said electrode adjacent the main hanging means, so that in case of breakage of the main hanging means, the auxiliary hanging means will still serve to support the electrode in the same vertical position and prevent it from falling down. According to the preferred construction, the weight of the electrode is normally supported principally or wholly by the main supporting means and at that time the auxiliary hanging means is ineffective for supporting purposes. In case of breakage of the main hanging means, however, the weight of the electrode is transferred to the auxiliary hanging means.

The invention may be applied to any suitable form of discharge or collecting electrodes in electrical precipitation apparatus.

The accompanying drawings illustrate various means of applying my invention to the support of a wire discharge electrode. and each figure of said drawings is aside elevation of the upper portion of the electrode and the supporting means therefor, with the fixed support on which the hanging means rest shown in cross section.

In Fig. 1, the wire or other linear member 1 of relatively small diameter, constituting the discharge electrode, is hung from a supporting member 3 by means of a loop 2 formed at the upper end of said wire and passed over said supporting member and secured as by means of clampin sleeve or collar 12. Said loop constitutes the main hanting means for the electrode and normally supports the entire weight thereof in such manner that the electrode hangs in a vert cal position. The auxiliary hanging means com-' prises a wire 5 having a loop 4 formed at the upper end thereof and extending around. but normally out of effective supporting contact with. the supporting member the two sides of said loop beii igsecured as by means of clamping collar or sleeve 13.

of the auxiliary hanging wire 5 is connected to the electrode wire 1 below the main hanging means in any suitable manner as for example l y neans of clamping collar or sleeve 6.

It will be evident that the loop 2 ordinarily supports the weight of the electrode wire, but that if a break should occur in the loop 2 or in the wire 1 above the point of connection of the auxiliary hanger thereto, the electrode willbe caught and supported by the auxiliary hanger which will then straighten out into substantially the former position of the main hanging means and thus prevent the electrode from falling and will support the electrode in the same vertical position as before.

In the operation of electrical precipitators in'which the electrodes, and particularly the discharge electrode wires or members, are hung by only a single hanging means, breakage of such single hanging means permits the electrode to fall and may cause serious electrical disturbances due to contact thereof with both the high tension electrode system and the low tension electrode system. By means of this invention, however, such electrical disturbances arising from breakage of the electrodehanging means it being understood that the hanging means may be inspected from time to time and any electrodes whose main hanging means has broken, so that the electrode is then supported only by the auxiliary hanging means, may be removed during times of shut-down of the apparatus and replaced by a new electrode having as above described.

In the construction shown in Fig. 2. the main hanging means is the same as described in Fig. 1, but the auxiliary hanging means comprises a loop 7 formed by a wire 8 whose two ends means of a clamping collar or sleeve 6. The loop 7 extends over, but normally out of effective supporting engagement with, the

supporting member 3. but is adapted to en- 9 gage said supporting member and catch the electrode in case the main supporting means should break.

As shown in Figs. hanging means may,

3 and 4, the auxiliary if desired, be provided are prevented,

double provision for support are secured to the electrode 1 by by a continuation or prolongation of the main electrode wire after passing through clamping means 12. Such continuation is bent upwardly and carried over the supporting member 3 to form a loop 14, and may then be carried downwardly and secured to the main portion of the wire in any suitable manner, for example, by means of clamping collar or sleeve 6 as shown in Fig. 3, or by soldering, welding or otherwise directly securing the same to said wire as shown at 9 in Fig. 4.

It will be evident that the invention is not restricted to the examples'above described, but is subject to numerous changes or modifications as long as the stated purpose is achieved, namely, the catching of the electrode and preventing it from falling in case of breakage of the main hanging means and providing for maintaining the electrode in the same vertical position as it occupied before the break. The importance of so maintaining the electrode in the same vertical position arises from the fact that the electrode has to be carefully centered between the opposing electrodes, and it is therefore desirable to maintain the electrode in substantially the same vertical position after the break as it occupied before the break so as to insure that the electrode will still be in substantially a central position between "the opposing electrodes, and will therefore maintain the operativeness of the precipitator until the opportunity arises for repairing the break.

I claim:

1. In an electrical precipitator, an electrode member, a supporting member, a main hanging means normally supporting said electrode member on said supporting member in such manner that the electrode member hangs vertically, and auxiliary hanging means connected to said electrode member adjacent the main hanging means and adapted to support said electrode member in the same vertical position in case of breakage of the main hanging means.

2. In an electrical precipitator, a discharge electrode member, a supporting member, hanging means normally supporting said electrode member on said supporting member in such manner that the electrode member is supported in vertical position and auxiliary hanging means connected to said elec trode member adjacent said first named hanging means and normally out of effective supporting engagement with said supportmg member but adapted to engage said supporting member and support said electrode member in the same vertical position in case of breakage of said first named hanging means.

3. In an electrical precipitator, a construction as set forth in claim 3, said first named hanging means comprising a loop at the upper end of said discharge electrode member and extending over said supporting Ill
